What this buck regulator does and where it fits
The MAX20076ATCB/V+ is a step-down buck regulator with synchronous rectification, delivering a programmable output from 1V to 10V at up to 1.2A. Its input range spans 3.5V to 36V.
Programmable output from 1V to 10V
The output is programmable via a feedback divider, with a minimum fixed reference of 1V and a maximum of 10V.
1.2A output — sizing the load budget
The 1.2A continuous output rating sets the ceiling for your downstream load. That is enough for a single sensor node, a low-power MCU plus a few peripherals, or a small relay coil. If your load peaks above 1.2A, you need a larger regulator or an external pass element. The synchronous rectifier helps keep the dropout low at full load, but the thermal limit of the 12-TDFN package still governs — adequate PCB copper and thermal vias under the exposed pad are required to sustain 1.2A at elevated ambient temperatures.
0°C to 70°C — commercial temperature grade
The operating temperature range of 0°C to 70°C limits this part to indoor, climate-controlled environments.
Lifecycle and compliance — active, no LTB risk
The MAX20076ATCB/V+ is listed as Active with ROHS3 compliance.
